Elixir - Comparision Operators
The comparison Operators in Elixir are mostly common to those provided in most other languages. The following table sums up comparison operators in Elixir. Assume variable A holds 10 and variable B holds 20, then −
| Operator | Description | Example |
|---|---|---|
| == | Checks if value on left is equal to value on right(Type casts values if they are not the same type). | A == B will give false |
| != | Checks if value on left is not equal to value on right. | A != B will give true |
| === | Checks if type of value on left equals type of value on right, if yes then check the same for value. | A === B will give false |
| !== | Same as above but checks for inequality instead of equality. | A !== B will give true |
| > | Checks if the value of left operand is greater than the value of right operand; if yes, then the condition becomes true. | A > B will give false |
| < | Checks if the value of left operand is less than the value of right operand; if yes, then the condition becomes true. | A < B will give true |
| >= | Checks if the value of left operand is greater than or equal to the value of right operand; if yes, then the condition becomes true. | A >= B will give false |
| <= | Checks if the value of left operand is less than or equal to the value of right operand; if yes, then the condition becomes true. | A <= B will give true |
Example
Try the following code to understand all arithmetic operators in Elixir.
a = 10
b = 20
IO.puts("a == b " <> to_string(a == b))
IO.puts("a != b " <> to_string(a != b))
IO.puts("a === b " <> to_string(a === b))
IO.puts("a !== b" <> to_string(a !== b))
IO.puts("a > b " <> to_string(a > b))
IO.puts("a < b " <> to_string(a < b))
IO.puts("a >= b " <> to_string(a >= b))
IO.puts("a <= b " <> to_string(a <= b))
When running above program, it produces following result −
a == b false a != b true a === b false a !== b true a > b false a < b true a >= b false a <= b true
